Answer:

The answer to your question is z = -3

Step-by-step explanation:

Expand                 42 = -7(z - 3)

                             42 = -7z + 21

Simplify                 7z = -42 + 21

                             7z = -21

Clear z                    z = \frac{-21}{7}

                              z = -3

Answer:

B

Step-by-step explanation:

Let's arrange the data set in increasing order.

We have 19, 27, 27, 33, 45, 53. The median is (27 + 33) / 2 = 30.

The new set is 19, 27, 27, 33, 45, 53, 90. The new median is 33.

Since 33 - 30 = 3 the answer is B.

8090 [49]

Answer:

g(x) = -|x|

Step-by-step explanation:

Are you familiar with the absolute value function y = |x|?

Its graph is v-shaped and opens up.

If the graph is turned upside down (so that it opens down), then g(x) = -|x|.

Help me please with my math

Answer:

P = 47.1 units

Step-by-step explanation:

the perimeter of the pair of straight opposite sides is 11+11, or 22

now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer

Circumference of circle with diameter of 8:

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

now add 22 + 25.13 to get 47.1 rounded to nearest tenths place

Someone help pls -……
uysha [10]

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

   36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d)  After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°
